Why does air planes have a life vest instead of parachute

In all, it takes place during the accident or landing on aircraft. Meanwhile, there is no need for parachute.

Another important point, passenger aircraft go very high and go too fast. In the meantime, it is impossible to jump from the plane and even open the door (10,000 meters, etc.). When the door is opened, it is necessary to attach an oxygen mask. Assuming that the door is opened, even in the minibus queue, the crowd of 200 people crushes each other. Even if we accept that everyone is in line to jump from the plane, everyone is jumping in 3 seconds, 600 seconds for 200 people in total. This makes a total of 10 minutes. Can you imagine that the passengers are waiting in 10 minutes!.

If the passengers were given parachutes, they would probably pull the rope in every panic and fill it with parachute piles. It should be opened at least 10 seconds after jumping parachute and it is very difficult to teach it with a short training. Even if there is a possibility of jumping parachutes, it is very difficult for elderly and children to open parachutes. It requires at least one month of education and experience. Imagine those who pulled the rope in the mouth of the door and opened the parachute, either on the engines, or on the wings. Passenger aircraft are not parachute aircraft, it is not equipped for jumping.

In case of an accident on the aircraft, the pilots try to descend to a flat surface with the least possible damage, while the passengers are dressed vests, so that the impacts are intended to prevent the important organs of the body. Oxygen masks automatically open and fall towards the passengers in case of opening any holes on the plane. On the plane, you first put your Kensi mask, otherwise: it is possible to fainting and both of you to be ineffective while you are trying to save your child. If your child can wear a mask, he is a separate topic.
